DTC P0339 Crankshaft Position Sensor Circuit Intermittent

CIRCUIT DESCRIPTION

DTC Detecting Condition:

Crankshaft position sensor (NE signal) consists of a magnet, iron core and pickup coil. The NE signal plate has 34 teeth and is installed the crankshaft timing pulley. The NE signal sensor generates 34 signals at every engine revolution. The ECM detects the crankshaft angle and engine revolution by the NE signal. In addition to them, the ECM detects distinction of the cylinder and phase of the VVT by combining the G (VV) signal with the NE signal.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

Component Operating Rang:

If there is no signal from the crankshaft sensor even though the engine is revolving, the ECM interprets this as a malfunction of the sensor.

INSPECTION PROCEDURE

HINT:
- Perform troubleshooting of DTC P0335 first. If no trouble is found, troubleshoot the given mechanical systems.
- Read freeze frame data using OBD II scan tool or hand-held tester. Because freeze frame records the engine conditions when the malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.
